I have an older machine, with two identical 80GB IDE harddisks. Unfortunately it is not 64bit so I grabbed the 32bit server RC iso and installed on the two, with 1-1 big raid partition (sda1/sdb1 , and RAID1, without swap, and ext4 on it.

The exact steps:

- create bootable USB stick with 10.04-rc server 32bit on it (I've created this with Karmic)
- boot the system from the USB, install
- partitioned the two disks manually for sda1/sdb1 as RAID partitions (no swap)
- created md0 as a RAID1 raid
- md0 mounted as / (root partition) with ext4 (everything else left as default)
(aswered 'Yes' when asked if I wanted to boot in case of degraded RAID)
- installed the system
- reboot, everything is fine, checked /proc/mdstat and the RAID was indeed sync'ing, but it did boot and no mention of md0pX

A small note: I didn't see ANY kind of messages during the boot, no GRUB menu, no nothing, just a cursor in the upper left, then the login prompt. A bit strange ;)
